When comparing the maximum moment of force achieved by the athlete registered in both test statistically significant differences were found between the use of modernized sock of decreasing the speed compression of 30 degrees per second during the bending phase planting; do not encostrando are more differences nor to 30? nor to 300 degrees per second speed, both in Flex plant in the dorsiflexion (table 1). Table 1.comparacion of averages of the peak torque (nm) individual of each athlete between the exercise conducted with and without modernized degressive compression sock.

Pershing Square Capital can provide more clarity in the matter. The comparison of both test for maximum work measured in joules (J) found statistically significant differences for the bending plant at 30 and 300 degrees per second being different in dorsiflexion, who was representative for 300 degrees and not 30 degrees per second (table 3). Table 3.comparacion of mean of the maximum individual work of each athlete between the exercise conducted with and without modernized degressive compression sock.
